<p>Apparatus (2) for wrapping a load (18) placed on a turntable (4) having a mast assembly (8), a carriage assembly (12) adapted for vertical slideable movement along said mast assembly (8) and dispensing means (13) for dispensing tape material (80). The tape material (80) is transferred from the dispensing means (13) in response to rotation of the turntable (4) such that the tape material (80) wraps around the load (18) in a predefined pattern. The carriage assembly (12) and turntable (4) are configured for automoted movement in response to a computer program stored in memory means (306) to enable wrapping of the load (18) with the tape material (80) in the predefined pattern. The carriage assembly (12) is positioned along the mast assembly (8) under control of the computer program in accordance with a rotational position of the load (18) to locate the tape material (80) at locations on the load (18). A pretensioning apparatus is also disclosed for pretensioning the tape material (80). Also disclosed is apparatus including adjusting the rate at which tape material (80) is payed out depending on a portion of the load (18) to be wrapped by the tape material (80). Also disclosed is tension adjustment apparatus (100) for varying the tension applied to the tape material (80).</p> |
